The controller 51 includes a processor (not illustrated) and storage 52. The processor includes for example a central processing unit (CPU).

The storage 52 includes read only memory (ROM), random access memory (RAM), and a secondary storage device. The secondary storage device is a nonvolatile storage device whose examples include a hard disk drive and flash memory. The ROM of the storage 52 stores therein different computer programs to be executed by the controller 51. The controller 51 loads the different computer programs stored in the ROM into the RAM to execute the computer programs, thereby realizing functions of the controller 51.

The operation display section 400 will next be described with reference to FIG. 3 . FIG. 3 is a partial enlarged view of the operation display section 400. As illustrated in FIG. 3 , the operation display section 400 includes a display section 410 and an operation key section 430.

The display section 410 includes a liquid crystal display (LCD). As one example, the display section 410 is a touch panel having a display function and an input function of detecting a touch operation. The display section 410 displays different operation images under control of the controller 51. Different execution commands are entered in the controller 51 as a result of the user touching the operation images on the display section 410.

The operation key section 430 allows the user to enter therethrough an input operation. The operation key section 430 includes a start key 432, a numeric keypad 433, function switching keys 434, and a reset key 435.

The start key 432 allows the user to enter therethrough an instruction to start an operation such as a copy operation or a scan operation. The numeric keypad 433 allows the user to enter therethrough an instruction representing the number of copies. The function switching keys 434 allow the user to enter therethrough an instruction to switch between functions. Here, the functions include a printing function, a copy function, a scanner function, and a FAX function. The reset key 435 allows the user to enter therethrough a reset operation.

Information stored in the storage 52 will hereinafter be described. The storage 52 stores therein information on multiple setting items for each of functions whose examples include the printing function, the copy function, the scanner function, and the FAX function, in order that the user obtains a target image. The multiple setting items are items on an image. The multiple setting items represent for example magnification settings, color settings, and N-in-1 (combine) settings.

A setting is set for each of the setting items at a timing according to an input operation from the user. Examples of the timing include immediately before the user obtains the target image. That is, one or more settings are newly set so that a desired target image is obtained. For example, the user sets “100%” as a setting at the magnification settings, sets “full color” as a setting at the color settings, and sets “2-in-1” as a setting at the combine settings, thereby enabling obtaining the target image.

Not that a setting at the “magnification settings” is for example a numerical value (for example “100%”) representing the size of the target image with the size of the document being 100%. Examples of the setting at the “color settings” include a setting representing a full color mode (“full color”), a setting representing a monochrome mode (“monochrome”), and a setting representing an automatic color mode (“automatic color”).

The storage 52 further stores therein information on category items (for example six category items). The multiple setting items are classified into any one of the category items.

A method of changing a setting entered in a setting item will next be described with reference to FIGS. 4 and 5 . The changing of the setting is performed by using an operation image displayed on the display section 410. The operation image includes a category item list image 701 and detailed setting images 702 (each of which corresponds to a second image). The category item list image 701 represents a list of category items. Each detailed setting image 702 represents a setting item.

The detailed setting images 702 will first be described. FIG. 4 illustrates a detailed setting image 702 representing a setting item “Combine”. As illustrated in FIG. 4 , the detailed setting image 702 includes a header area 702 d, an “Off” button 702 a, a “2-in-1” button 702 b, and a “4-in-1” button 702 c. The header area 702 d includes a “cancel” button 702 e, an “OK” button 702 f, and a heading “Combine” 702 g. The “Off” button 702 a is a button for setting one page sheet to be printed on each page of paper. The “2-in-1” button 702 b is a button that causes the image forming section 33 to form two pages of a print target on one page sheet of paper. The “4-in-1” button 702 c is a button that causes the image forming section 33 to form four pages of a print target on one page sheet of paper. The detailed setting image 702 allows the user to set any one of a setting “Off”, a setting “2-in-1”, and a setting “4-in-1” in the setting item “Combine” according to an input operation by the user.

FIG. 5 illustrates the category item list image 701. As illustrated in FIG. 5 , the category item list image 701 includes a navigation area 703 and a main area 704. The navigation area 703 includes category item images (for example six category item images) 703 a to 703 f (each of which corresponds to a first image). Each of the category item images 703 a to 703 f represents a category item. The category item images 703 a to 703 f respectively represent for example a “Quick Setup” button 703 a, an “Org./Paper/Finishing” button 703 b, a “Layout/Edit” button 703 c, a “Color/Image Quality” button 703 d, an “Advanced Setup” button 703 e, and a “Favorites” button 703 f.

The main area 704 includes multiple setting item images 704 a to 704 c. The multiple setting item images 704 a to 704 c represent for example a “Zoom” button 704 a, a “Combine” button 704 b, and a “Margin/Centering” button 704 c, respectively. Each of the multiple setting item images 704 a to 704 c represents a setting item. Note that the size of the main area 704 is determined according to the size of the display section 410. The main area 704 cannot however display the whole number of the setting item images because the setting item images are large in number. The main area 704 accordingly displays a predetermined number of setting item images 704 a to 704 c of the multiple setting item images. The predetermined number of setting item images 704 a to 704 c to be displayed in the main area 704 are switched as a result of the user performing an up or down scroll operation.

A configuration of the controller 51 will then be described with reference to FIGS. 2, 4, and 5 . The controller 51 includes a display controller 511 in addition to the storage 52.

The display controller 511 controls the display section 410 so as to cause the display section 410 to display the category item list image 701 or a detailed setting image 702 based on an input operation. The display controller 511 first causes the display section 410 to display the category item list image 701 (see FIG. 5 ). The user pushes one category item image of the category item images 703 a to 703 f, and the display controller 511 then scrolls an image of the main area 704. Thus, the display controller 511 causes the display section 410 to display, in the main area 704, the setting item images 704 a to 704 c, representing setting items belonging to the category item, of the multiple setting item images. For example, when the “Layout/Edit” button 704 c is pushed, the image displayed in the main area 704 is automatically scrolled. As a result, for example, the “Zoom” button 704 a, the “Combine” button 704 b, and the “Margin/Centering” button 704 c, representing setting items belonging to a category item “Layout/Edit” are displayed in the main area.

In contrast, the user pushes one setting item image of the multiple setting item images 704 a to 704 c, and the display controller 511 then switches between images. That is, the display controller 511 causes the display section 410 to display a detailed setting image 702 associated with the one setting item image 704 a to 704 c (see FIG. 4 ). For example, an image of the display section 410 is switched when the “Combine” button 704 b is pushed. That is, the display section 410 displays the detailed setting image 702 representing the setting item “Combine”. Here, the category item list image 701 is displayed in an upper layer for the detailed setting image 702. The setting item images 704 a to 704 c displayed in the upper layer are associated with the detailed setting image 702 displayed in a lower layer.

When the user pushes the “Off” button 702 a to the “OK” button 702 f with the detailed setting image 702 displayed, one or more settings entered in the setting item are changed. In the present embodiment, according to a setting item that has been entered, the display controller 511 controls the display section 410 so as to cause the display section 410 to display a predetermined image 705 in a corresponding first image. Specifically, when one or more settings are changed, the display controller 511 controls the display section 410 so as to cause the display section 410 to display the category item list image 701 to which one or more predetermined image 705 are added. Moreover, the display controller 511 causes the storage 52 to store therein the predetermined image 705 and the changed setting item with the predetermined image 705 associated with the changed setting item.

FIG. 6 illustrates the category item list image 701 in which one mark image 705 (predetermined image) is displayed. As illustrated in FIG. 6 , the one mark image 705 is further displayed at the upper right of the category item image 703 c. The mark image 705 is displayed in the category item image 703 c representing the category item to which a corresponding setting item belongs. Examples of the predetermined image 705 include a circle mark image, a quadrilateral mark image, an arrow image, and a frame image. The mark image 705 is displayed, so that the user can recognize that one or more settings entered in one or more setting items belonging to the category item have been changed. This enables the user to easily find the setting item image 704 a to 704 c representing the setting item whose setting has been changed, and the detailed setting image 702.

FIG. 7 illustrates the category item list image 701 in which mark images 705 are displayed. As illustrated in FIG. 7 , three mark images 705 are displayed on the right of the category item image 703 c. The three mark images 705 depicted in FIG. 7 are displayed, so that the user can recognize that the settings entered in three setting items (same number as the number of mark images 705) belonging to the category item have been changed.

In addition, according to any of the mark images 705 touched, the display section 410 is controlled by the display controller 511 so as to display corresponding second images. Specifically, when any of the mark images 705 is pushed, the display controller 511 controls the display section 410 so as to cause the display section 410 to display the setting item images 704 a to 704 c associated with the mark images 705. For example, when the mark image 705 on the upper right in the category item image 703 c is pushed, the display controller 511 scrolls the image of the main area 704. That is, the display controller 511 causes the display section 410 to display, in the main area 704, the setting item images 704 a to 704 c associated with the mark images 705. This enables the display section 410 to display, in the main area 704, the setting item images representing the setting items whose respective settings have been changed, of the multiple setting item images 704 a to 704 c. The display controller 511 may further cause the display section 410 to display a detailed setting image 702 associated with any of the setting item images 704 a to 704 c. Note that the display controller 511 scrolls the image of the main area 704 when an area of the category item image 703 c other than the mark images 705 is pushed. That is, the display section 410 displays, in the main area 704, the setting item images 704 a to 704 c representing the setting items belonging to the category item.

A process of the controller 51 in the present embodiment will next be described with reference to FIG. 8 . FIG. 8 is a flowchart depicting the process of the controller 51 in the present embodiment. The process of the controller 51 includes Steps S101 to S104. As illustrated in FIG. 8 , at Step S101, the display controller 511 first causes the display section 410 to display the category item list image 701.

Then at Step S102, when the user pushes a setting item image 704 a to 704 c, the display controller 511 causes the display section 410 to display a corresponding detailed setting image 702.

Then at Step S103, when the user performs an input operation to enter a setting in a detailed setting image 702, the display controller 511 changes a setting entered in a corresponding setting item.

Then at Step S104, the display controller 511 controls the display section 410 so as to cause the display section 410 to display a mark image 705. The mark image 705 is displayed in a category item image 703 a to 703 f representing the category item to which the setting item belongs. After the display controller 511 controls the display section 410 so as to cause the display section 410 to display the mark image 705 in the category item image 703 a to 703 f, the process ends.

As described above with reference to FIGS. 1 to 8 in the present embodiment, the category item list image 701 includes a category item image 703 a to 703 f to which one or more mark images 705 are added. It is therefore possible to easily find one or more setting item images 704 a to 704 c representing one or more setting items whose respective settings have been changed, and corresponding detailed setting images 702.

As above, the embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the above-described embodiment and can be practiced in various ways within the scope without departing from the essence of the present invention (for example, (1) to (3) below). The drawings mainly illustrate schematic constituent elements in order to facilitate understanding, and properties such as thickness, length, numbers or the like of each constituent element illustrated in the drawings may differ from actual properties thereof in order to facilitate preparation of the drawings. Further, the shape, dimensions, and the like of each constituent element described in the above embodiment are merely examples that do not impose any particular limitations and may be altered in various ways as long as such alterations do not substantially deviate from the configuration of the present invention.

(1) In the present embodiment, when one or more settings are changed, the display controller 511 causes the display section 410 to display one or more mark images 705 in a corresponding category item image 703 a to 703 f. Alternatively or additionally, when one or more settings are changed, the display controller 511 may cause the display section 410 to display a numerical image 706 in a corresponding category item image 703 a to 703 f.

FIG. 9 illustrates the category item list image 701 in which the numerical image 706 is displayed. As illustrated in FIG. 9 , the numerical image 706 is displayed on the right of the category item image 703 c. In the present embodiment, the numerical image 706 represents the numeral 6. That is, displaying the numerical image 706 enables the user to recognize that respective settings have been changed at six setting items belonging to the category item. The display controller 511 may further include a determination section. The determination section determines the number of settings that have been changed. The determination section causes the display section 410 to display one or more mark images 705 if the number of settings that have been changed is less than a predetermined number, and to display the numerical image 706 if the number of settings is greater than or equal to the predetermined number.

(2) In the present embodiment, one or more mark images 705 are displayed in the category item list image 701 that is displayed in the upper layer for the detailed setting image 702. Alternatively, when a top layer image is displayed in an upper layer for the category item list image 701, one or more mark images 705 may be displayed in the top layer image.

(3) In the present embodiment, the image forming apparatus 1 is not limited to the multifunction peripheral. Examples of the image forming apparatus 1 may further include a copier, a facsimile machine, and a printer. Although the configuration where the image forming apparatus 1 is provided with the display control device 10 has been described, the invention is not limited to this.
